TL;DR
Honcho is open-source memory infrastructure for stateful AI agents, built by Plastic Labs and released under a permissive license. It's currently trending on GitHub — 4,301 stars total with 644 new stars this week — and it just posted state-of-the-art numbers on three independent agent-memory benchmarks. The highlights:
Reasoning-first memory: extracts conclusions from conversations and events, not just chunks to match later
Peer-centric model: users, AI agents, groups, projects, and ideas are all first-class "peers" that change over time
